Patent number: 9292150Abstract: A display control system for a multi-layer display system including at least one multi-layer display unit. A multi-layer display unit includes multiple stacked or overlapped display layers each adapted to render display elements thereon for viewing through the uppermost display layer. The level of difficulty for a user to view an overlapped image differs depending on the color, brightness or type of images (for example text-on-text) being displayed and also the layer in which the image is being displayed and whether the image is currently active. At least any overlapping portion of display elements from different display layers are adjusted (automatically or by a user) in order to improve the viewing experience for a viewer. Types of adjustment possible include moving the images within their display layer or to an alternative display layer or altering their visual properties (such as color, brightness, contrast, etc.).Type: GrantFiled: April 10, 2012Date of Patent: March 22, 2016Assignee: PURE DEPTH LIMITEDInventors: Gabriel Damon Engel, David John Ferguson, Harnish John Ogilvie MacLeod, Bruce David Seymour

Patent number: 8941691Abstract: A method, system, computer software and display for generating and displaying a target image (14) on a multi-layered display (1). The target image (14) includes a graphical object (9) displayed on a first display layer (2) of the multi-layered display (1) and contextual elements (10) displayed on a second display layer (3). The graphical object (9) is provided with a peripheral boundary region (12) composed of contextual elements (10) displayed on the second display layer (3). A projection of the peripheral boundary region (12) on the first display layer (2) demarcates a silhouette (11) on the second display layer (3).Type: GrantFiled: August 26, 2009Date of Patent: January 27, 2015Assignee: Pure Depth LimitedInventor: James Baron

Patent number: 8928682Abstract: Image processing may be performed to generate a color image for display on a color display screen and a monochrome image for display on a monochrome display screen, where an overlap of the images may produce a resultant color image at one or more depths. The one or more depths may be determined by an amount of blur applied to one image and an amount of sharpness applied to other. The one or more depths may be determined by a gamma value of the monochrome image. Since the monochrome display screen may have fewer or no color filters and/or a lower resolution, the monochrome display screen may pass more light than conventional color display screens. As such, less light can be used to illuminate color images displayed at different depths using a color display screen and a monochrome display screen, thereby reducing energy consumption of the display device.Type: GrantFiled: July 6, 2010Date of Patent: January 6, 2015Assignee: Pure Depth LimitedInventors: Gareth P Bell, Darryl Singh, Hayden James Rosser

Patent number: 8432411Abstract: A method, computer-usable medium, and system for processing graphical data for display on a multi-component display is disclosed. Embodiments improve the display quality of multi-component displays by modifying graphical data to preemptively compensate for distortion caused by interstitial layers and/or display screens of the multi-component display, thereby enabling display of graphical objects from multi-component displays with improved optical characteristics. For example, where components of a multi-component display blur displayed images, graphical data used to display graphical objects may be modified to sharpen the graphical objects before display. The pre-sharpening amplifies the high frequency components of the displayed graphical objects to compensate for the dampening caused by passing the graphical objects through the components of the multi-component display.Type: GrantFiled: May 18, 2007Date of Patent: April 30, 2013Assignee: Pure Depth LimitedInventors: Gareth Paul Bell, Daniel E. Evanicky, Edward Maurice Granger

Patent number: 8154691Abstract: A matte surface of a display screen is converted to an optically flat surface, for example, via an epoxy resin coating or the like which has a refractive index equal to that of the matte surface. A film with a substantially flat surface may be applied to the matte surface. Alternatively, the matte surface may be removed from the screen, and replaced with an optically smooth surface. The matte surface may be a diffusive surface formed on a birefringent film of an LCD screen. The display screen is the front screen of a multilevel three-dimensional display comprising layered screens, and altering the surface from matte to flat reduces the blurring of displayed images.Type: GrantFiled: March 11, 2008Date of Patent: April 10, 2012Assignee: Pure Depth LimitedInventor: Mark John Searle
